WALL CONSTRUCTION.

Specification of Letters Patent.

Application led June 6, 1910. Serial No. 565,194.

To all whom 'it may concern:

Be it known that I, ROBERT TINsLnY, a citizen of the United States, residing at Chicago, in the c ountyof Cook and State of Illinois, have invented certain new and useful Improvements in Wall Constructions, of which the following is a specification.

This invention relates to wall constructions and aims to produce a substantial and durable wall particularl adapted for rail Way cars in general, an more particularly for railway baggage cars.

The walls of baggage cars, particularly the inner walls are subjected to vary hard usa e in the transportation of bagga e, due to t e corners of lar e and heavy trun s and boxes striking and alling against them and. the frequency with which the wooden walls' of comparatively, new baggage cars were split and broken in this manner has led to the general adoption of sheet metal lining for the cars. Flat sheet metal, however, is

.very easily dented and bent, and in order that it might be stiff enough to withstand the shocks and concussions incident to the handling of baggage, it has heretofore been necessary to make the metal -l lining very thick and heavy. In addition to increasing the initial cost of the cars because of the expensiveness lof heavy sheet metal, the walls constructed of -heavy metal increase the weight of the cars, thereby unnecessarily increasing the cost of haulingthem.

.It is 'an object of my presentinvention to provide a car wall construction for use in baggagecars which will be light in weight `,and at the Same time strong and durable,

- and which will notbe readily bent or dented.

'can be readily placed in -position a Another object iis toprovide a sheet metal -wall having Straps or protecting strips ex tendlng longitudinally thereof on its inner face, Awhich serves the dual purpose of securing the metal sheet in place anda'ording protection to its inner surface.

An additional object ofv the invention is the provision of -a wall or wall linin which iter. the

car is assembled, and which can vbe easily removed and replaced or repaired as occasion 5o requires.

Still another object is the rovision of mproved lmeans for removab y securing the metal sheet and straps to the vertical wall posts. j t v The inventlon has other objects and advbolt to vantages which will' be readily understood from the following description when taken Patented May 23, 1911.

thereof, in which- Figure l is an elevation of a section of the inner face of a wall embodying my invention. Fig. 2 is a vertical sectlon thereof.

ig. 3 is an enlarged detail view showing the manner of fastenin the wall to a post. Figs. 4, 5, 6 and 7 s ow modified forms of the upright posts; and, Fig. 8 is a fra mentary elevation showing one of the bo t receivin openings with which the posts are provide On the drawings, 9 indicates a side sill of a car, which may be made in any of the well known and usual forms carrying the floor 10 and having secured thereto the upright posts 11', by the usual rivets or bolts 12. The outer wall 13 of the car may be secured to the upright posts in any preferred manner, depending to a considerable extent upon the shape of the posts employed.

In Figs. 2 and 3,the post 11 is shown simply as an angle-bar. In Fig. 4 I have shown a modified form of post 14 which is of Z-bar formation. Another modification 15 is disclosed in Fig. 5 which is constructed'in an L-shape. Fig. V6 illustrates another modification showing a post 16 constructed in the form of a channel-bar; andFig. 7 shows still.

another modification of a post 17 of T-bar configuration. It will be obvious that many other forms of post might be employed, the only feature which is material to this invention residing in the fact that the inner ed e of the post should provide a substantial y flat face extending transversely of the post which can be provided with a bolt receiving opening 18. t

An' enlarged view ofthe bolt receiving 'opening 18 is shown in Fig. 8, from which 1t will be seen that the opening comprises a circular part 19 of sufficient size to receive the head 20 of aV bolt, and is extended at its lower vside into a substantially square slot 21 to accommodate the square shank 22 of the prevent the bolt from turning inthe opening.

Upon they inner faces of the upright posts there is disposed a sheet'of corrugated metal having the corrugations prefera ly extending avertical directionparallel withthe upright posts.` The sheetmay be Imade of ,respond to the'spacing o` the upright posts sufficient size to cover one wall of a caror it may be madevin sections of any preferred size and -shape adapted to be placed in position to forma complete covering or lining Ifor the vertical walls of the car. A plurality ofmetal straps or strips'24is disposedy transversely of the corrugations and of the upright posts upon theinner surface of the corrugated sheet. The strapsare bent at intervals throughout their len th, spaced to 'corto provide depressions 25. These v depressions, as will be evident l.from Fig. 3,.are adapted to fit inthe depressions in the surface of .the'co'rrugated sheet. The depressed 'portionsof the straps are provided with 'bolt receiving openings adapted to be alined with the bolt holes or openings 18 in the posts.

e, The/sheet 23 is also provided with bolt receiving openings'spaced to be alined with the bolt holes or openings inthe-posts. The fastening bolts designated generally as26, project inwardly from the inner .face of the post through the corrugatedfsheet '23 and the straps 24. A washer-,27 is preferablypositioned upon the lbolt betweenv the corrugated sheet and the strap .to rmly bindthe sheet to the post when the fastening nut 28 yis threaded upon the bolt.

It will be evident from the above description that the car may be assembled Awith the upright posts in position and the outer walls ofthe 'car fixed in place before the lining or ..bolts, and the fastening nuts'28 are yscrewed y as to maintain the sheet in position.

metal sheet is attached in-position'.

When the posts are-of such shape that it'A is inconvenient to insert the fastening bolts from the' rear of the ange, the head. 20,of

lthe bolt may be inserted through the enlarged portion 19 ofthe bolt reoelving openings in each post, and the shoulder 22 therevof engaged'in the angular slot 21. The cor-4 rugated sheet 23 or. sections thereof may now' be slipped over the projecting ends of the bolts, the Washers 2 areplaced upon the bolts, the ,straps 24 areengaged with the up 'to firmly clamp the sheet and straps to the posts. The'corru ated sheet is stronger than a plain sheet o the same Weight and is lighter than a plain sheet of the same strength. The straps which are-spaced apart vertically of the car, serve as a protection tothe inner face of the sheet as well The depressed portions 25 of the straps 'fit into the depressions in the corrugated surface; of the metal sheet and .provide a more rigid 'engagement between the straps and sheet,

and also render possible a construction in which the nuts or the bolts are readily Yaccessible on the inside of the `carbutin which the ends of the bolts ornuts thereon do not project into'the car beyond the innerface of the wall.

It will be evident fromthe above that the corrugated sheet orV section thereof maybe.

removed as occasion should require, `t`o be repaired or replaced by a new sheet or'sectionV without dismantling the car or disturbing the outer walls thereof. It will' also be evident thatlthecon'structio'n is capable of considerable variation in structural details from the modiication disclosed, without departing from the-spirit of the invention or sacrificing any of the material advantages. thereof,

therefore, I do not Wish ,to be limited to' the exact cons tructionshown andl described,-

but believe I am entitled to allsuch varia-A tions -thereof as properly come within the .scope -of the appended claims.

' What I desire to claim is:

Ina wall construction, the combination of 'upright posts, a metal sheetv disposed against the` posts, metal straps arranged on the inner face of said sheet, said straps being provided with depressed portions spacedl t-o coincide with the said posts, and bolts extending through said posts, ,metal sheet.

being extended intov a lsmaller angular p01*-,

tion to receive the shank of the bolt and prevent turning of thesarne, and a bolt engaged in said opening and extending through the metal sheet and strap, whereby thefsheet and strap are' secured 'to the post. l i

3. In a wall construction, the combination'v o'f upright posts, a corrugated metal sheet disposed against the posts, a plurality of metal straps having depressed portions adapted to fit into corrugations in `the sheet `and spaced apart` to coincide with the npright' posts, and means for connecting the sheet land Istraps to the posts.

'i 4. In a wall-construction, the combination l' of aplur'ality of upright posts, a metal sheet vertically corrugated, positioned against the inner` faces of said posts, a plurality of metal straps .disposed transversely of the posts andl L corrugations in `the sheet, each strap being provided with spaced apart 'de ressions each aving a bolt receiving hole t erein, and a' plurality of boltsl adapted to be engaged with the posts from the inner sidezthereof and extending inwardly fromy the posts through said sheet and straps, whereby the said sheet and straps are xedly secured to' the posts. y y

. 5.
